摘　　要：为探究不同级配条件下乳化沥青混合料的路用性能,文中以AC-13、AC-16乳化沥青混合料为主,对水泥含量为0、1%、2%和3%冷拌冷铺沥青混凝土低温性能、水稳定性能和高温性能差异展开试验分析。结果显示,AC-13和AC-16乳化沥青混合料掺加1%、2%水泥时高温性能良好,水泥掺量提升能够有效改良乳化沥青水稳定性、高温稳定性;同时也会导致混合料低温性能受到不利影响。综合考虑,推荐1.0%~1.5%为水泥最佳掺量。In order to explore the road performance of emulsified asphalt mixtures at different levels,AC-13 and AC-16 emulsified asphalt mixtures were mainly used in this paper.The low temperature performance,water stability and high temperature performance of cold mixed cold laid asphalt concrete with cement content of 0,1%,2%and 3%were tested and analyzed.The results show that AC-13 and AC-16 emulsi-fied asphalt mixtures have good high temperature performance when mixed with 1%and 2%cement,and the water stability and high tempera-ture stability of emulsified asphalt can be effectively improved by increasing the cement content.At the same time,the low temperature per-formance of the mixture will be adversely affected.Considering comprehensively,it is recommended that 1.0%~1.5%is the best cement content.
